1. Metal materials: such as steel, aluminum, copper, iron and other metals and their alloys. These materials are widely used in the engineering and manufacturing industries and it is crucial to test and quality control them for tensile strength, yield strength, elongation, etc.

1. Plastics and polymers: such as polyethylene, polypropylene, polyvinyl chloride (PVC), polyamide (nylon), polyester, etc. These materials are widely used in plastic products, packaging materials, automotive parts, etc., and tensile testing can evaluate their strength, elastic properties and fracture characteristics.

1. Rubber material: such as natural rubber, styrene-butadiene rubber (NBR), nitrile rubber (CR), silicone rubber, etc. Rubber products are widely used in automotive, aerospace, electronics, medical and other fields. Tensile testing can evaluate the tensile strength, elongation and fracture properties of rubber.

1. Fiber materials: such as natural fibers (cotton, hemp, silk), synthetic fibers (polyester fibers, nylon fibers) and high-performance fibers (carbon fibers, glass fibers, aramid fibers, etc.). Tensile testing of fiber materials can evaluate its strength, elongation at break and tensile properties, which is of great significance to industries such as textiles, clothing, and aerospace.

1. Composite materials: such as carbon fiber reinforced composite materials, glass fiber reinforced composite materials, metal matrix composite materials, etc. Tensile testing of composite materials can evaluate their strength, stiffness and fracture properties, and these materials are widely used in aerospace, automotive, sporting goods and other fields.

It is worth noting that the test methods and standards for each material may be different, so before conducting the 100kN tensile test, you should refer to relevant industry standards, specifications or test methods to ensure the accuracy and comparability of the test process .
